- Using a wireless power bank. Android phones will work with a completely dead/useless battery if they are plugged into a power bank. If your power bank doesn't work that way, then you need a new power bank.
- Using a different device. Of course your important files are on this phone. Do you think this phone will last forever? Backup those files to the cloud so you can access them from any device. You get free cloud storage with your Google account.
Instead of blaming all your problems on an external entity like Google, if you take accountability for solving your problem, you will find it is not nearly so intractable. Others here can offer advice, but it is ultimately up to you to decide on a course of action and pursue it. I wish you the best of luck.
